It seems like my smog pump has failed. Sounds like marbles in a can.

So until I can remove/replace it, I have decided to get a shorter belt and bypass it so my car sounds normal again.

I've been told that to bypass the smog pump I would need a 84.5" belt. So thats what I bought. The belt is loose, flapping around and squeals just off idle. It's installed correctly.

Can my tensioner be shot??

Did I buy the wrong size belt??

Is the 84.5" belt too long for underdrive pulleys??

I have A/C and PS still installed.

Thanks for your help.
